A couple years ago, every time there was gpu coil whine, it would get picked up by the motherboard and played out to my headphones. I ended up getting an rma/ sent in my board to gigabyte to get it fixed. In the end, I ended up getting a usb dac/ amp.
However, just recently, I noticed that there was a bit of hissing (only audible if no sound is being played, like loading screens/ menus) coming from the USB audio. It's definetly not as bad and annoying as the coil whine sound from the previous paragraph, but it's definetly from the same reason. Is there really anything I can do to fix this if it is a case of poor shielding?
Regarding coil whine (since the usb noise is related to coil whine) I know I can limit fps and use vsync. However, one of the major culprits is the game killing floor 2. There's no frame limit (except for the variable frame option that sets it to 62 fps... Not happening given its fast paced and I'm playing on 144hz), vsync input lag isn't something I like to deal with, and fps limiting programs like evga precision/ msi afterburner sometimes don't play nice with my games such as destiny 2.
